Automatic Train System

[dolmen62]

It don't work ! The train don't stop if I'm not in !

[AGENT_STEELMEAT]

Did you edit the code I posted properly? Post your script again.

[dolmen62]

well, I've an error when i modify "getrootelement"

function makeTrain(source) 
    loco = createVehicle(537,1725.9,-1954,16) 
    locool = createVehicle(538,1840,-1954,16) 
    setTrainDerailable(loco, false) 
    setTrainDerailable(locool, false) 
    removeStreamable( loco ) 
    removeStreamable( locool ) 
    local pilot1 = createPed(241,1693.38,-1959,15.6) 
    local pilot2 = createPed(241,1711,-1959,15.6) 
    warpPedIntoVehicle (pilot1, loco) 
    warpPedIntoVehicle (pilot2, locool) 
    removeStreamable( pilot1 ) 
    removeStreamable( pilot2 ) 
    createBlipAttachedTo(loco, 42) 
    setTrainSpeed(loco, 0) 
    setTrainSpeed(locool,0.203) 
    outputChatBox("Train is here", source, 255, 255, 0) 
    removeStreamable(markerGare2) 
    setTimer(depart, 20000, 1) 
end 
addCommandHandler("traintest", makeTrain) 
  
local markerGare2 = createMarker(787, -1341.8, -1.8, "cylinder", 3, 255, 255, 255, 5) 
function markerHit(hitElement, matchingDimension) 
     if matchingDimension and hitElement == loco then 
          setTrainSpeed(hitElement, 0) 
          outputChatBox("Your message here") 
          setTimer(depart, 20000, 1) 
     end 
    setTimer(depart, 20000, 1) 
end 
addEventHandler( "onMarkerHit", markerGare2, stop ) 
  
function depart () 
    setTrainSpeed(loco, 1) 
    setTrainSpeed(locool, 1) 
end 
  
function removeStreamable( theElement ) 
    triggerClientEvent( "removeStreamable", getRootElement(), theElement ) 
end 
  

[SDK]

Well, your addEventHandler for onMarkerHit points to the wrong function, "stop" instead of "markerhit'

[dolmen62]

No change, it don't stop.

Ok so I made few tests and I found the problem, the problem is that when we set the streamable of the trains to false, then ok there aren't streamed but their positions stay streamed. If I go to the 2nd station, I see the trains moving but not their positions. So their positions aren't updated but If I go to the position where they spawned, the position is "unstreamed" and the brake function works

Maybe someone can add this bug in bugtracker ( idk how to use it )

If you want to make a test, then take this:

Server:

function makeTrain(source) 
    loco = createVehicle(537,1725.9,-1954,16) 
    locool = createVehicle(538,1840,-1954,16) 
    setElementID( loco, "loco1" ) 
    setElementID( locool, "wagon1" ) 
    setTrainDerailable(loco, false) 
    setTrainDerailable(locool, false) 
    -- removeStreamable( loco ) 
    -- removeStreamable( locool ) 
    local pilot1 = createPed(241,1693.38,-1959,15.6) 
    local pilot2 = createPed(241,1711,-1959,15.6) 
    setElementID( pilot1, "pilot1" ) 
    setElementID( pilot2, "pilot2" ) 
    warpPedIntoVehicle (pilot1, loco) 
    warpPedIntoVehicle (pilot2, locool) 
    -- removeStreamable( pilot1 ) 
    -- removeStreamable( pilot2 ) 
    createBlipAttachedTo(loco, 42) 
    setTrainSpeed(loco, 0) 
    setTrainSpeed(locool,0.203) 
    outputChatBox("Train is here", source, 255, 255, 0) 
    removeStreamable( loco ) 
    setTimer(depart, 20000, 1) 
    nextgare = 1 
    setTimer( check, 2000, 0 ) 
end 
addCommandHandler("traintest", makeTrain) 
  
-- local markerGare2 = createMarker(787, -1341.8, -1.8, "cylinder", 3, 255, 255, 255, 5) 
function stop (hitElement) 
    -- outputChatBox("HIT") 
    if not( getElementType( hitElement ) == "vehicle" ) then return end 
    -- outputChatBox("c'est un véhicule") 
    if not( getElementModel( hitElement ) == 537 ) then return end 
    outputChatBox("Brake") 
    setTrainSpeed(loco, 0) 
    setTrainSpeed(locool, 0) 
    -- if ( source ) then 
        -- if ( source == markerGare2 )then 
            -- outputChatBox("Le Train est dans Market Station.", getRootElement(), 255, 255, 0) 
        -- end   
    -- end 
    setTimer(depart, 20000, 1) 
end 
-- addEventHandler( "onMarkerHit", getRootElement(), stop ) 
  
function depart () 
    -- nextgare = nextgare+1 
    setTrainSpeed(loco, 1) 
    setTrainSpeed(locool, 1) 
end 
  
function removeStreamable( theElement ) 
    outputChatBox( "remove_s") 
    triggerClientEvent( "removeStreamableLocos", getRootElement() ) 
end 
  
function check() 
    local x, y, z = getElementPosition( getElementByID( "loco1" ) ) 
    outputChatBox( x..", "..y..", "..z) 
    if nextgare == 2 then 
        if y >= -1341.8 then 
            stop( loco ) 
            nextgare = nextgare+1 
        end 
    -- elseif nextgare == 3 then -- a decommenter pour continuer 
        -- if   >=  then 
            -- stop( loco ) 
        -- end 
    end 
end 
  

Client:

addEvent("removeStreamableLocos", true ) 
function removeStreamableLocos( theElement ) 
    setElementStreamable( getElementByID( "loco1" ), false ) 
    setElementStreamable( getElementByID( "wagon1" ), false ) 
    setElementStreamable( getElementByID( "pilot1" ), false ) 
    setElementStreamable( getElementByID( "pilot2" ), false ) 
    outputChatBox("destream") 
end 
addEventHandler("removeStreamableLocos", getRootElement(), removeStreamableLocos ) 

So go to the the station underground of LS then type /traintest ( the T on the map is the train ) wait 10 sec then the train will move.

You will see that the position stay to 1725.9000244141, -1954, 16 and the train will not stop to the station.

ok so now go to the spawn position and then the position will instantanly change to another position.

[dolmen62]

I've test it, and it's really annoying ! We need a gost player ! But I don't know if it exist.

[Castillo]

A ghost player? maybe you could use a ped?

[karlis]

you mean a ped?

[dolmen62]

No ! A real player who is all the time in the train.

[Castillo]

Well, you won't get a player who will be there full time, so why not a ped?? do you know what a PED is?

[dolmen62]

Yes, I actually use it to control the train.

[dolmen62]

I change my system, now I use Timer.

My new problem is how to get in the train ! because it respawn when I want to get in !

[dolmen62]

Error found !!! Train's coordinates are used by the client, and not by the server !

[Wojak]

Ok so I made few tests and I found the problem, the problem is that when we set the streamable of the trains to false, then ok there aren't streamed but their positions stay streamed.

So their positions aren't updated but If I go to the position where they spawned, the position is "unstreamed" and the brake function works

Maybe someone can add this bug in bugtracker ( idk how to use it )

its not a bug, its a MTA sync limit (100m for peds, 140 for vehicles)

even if someone will "fix" this, you wont find a server that will handle it...

[DiSaMe]

I think this could be the solution: getElementPosition client-side --> triggerServerEvent with coordinates --> setElementPosition server-side.

[dolmen62]

Yes I Will try it today. But, if no body is connected to the server, what happen ?

[DiSaMe]

If nobody is connected to the server, then server has no player to sync the train, so it won't move, but there will be no players to see that anyway.

[dolmen62]

Thank you for your help. I Hope it work !

[dolmen62]

I don't know how to get client coordinates on the server.

[Castillo]

Do you mean send data to the server?

If so, then you can use triggerServerEvent function to send data.

[dolmen62]

No, coordinates don't change in the server, that's why I Want to take coordinates from the client, to the server. But I try to use triggerClientEvent, but it don't work.

I can't sens you code because I'm on my iPod.

[Castillo]

Well, I can't help you if don't post your code, also, you could also use setElementData and getElementData.

[dolmen62]

View my code :

Client side :

addEvent("getTrain", true ) 
function getTrain () 
    local x, y, z = getElementPosition(getElementByID( "loco1" )) 
    local a, b, c = getElementPosition(getElementByID( "wagon1" )) 
    local g, h, i = getElementPosition(getElementByID( "pilot2" )) 
    local d, e, f = getElementPosition(getElementByID( "pilot1" )) 
end 
addEventHandler("getTrain", getRootElement(), getTrain) 

Server side :

function setTrain (theElement) 
    triggerClientEvent( "getTrain", getRootElement()) 
    setElementPosition(loco, x, y, z, false) 
    setElementPosition(locool, a, b, c, false) 
    setElementPosition(pilot1, d, e, f, false) 
    setElementPosition(pilot2, g, h, i, false) 
end  

[Castillo]

Client side :

addEvent("getTrain", true ) 
function getTrain () 
    local x, y, z = getElementPosition(getElementByID( "loco1" )) 
    local a, b, c = getElementPosition(getElementByID( "wagon1" )) 
    local g, h, i = getElementPosition(getElementByID( "pilot2" )) 
    local d, e, f = getElementPosition(getElementByID( "pilot1" )) 
    triggerServerEvent("setTrainPosition",getRootElement(),x,y,z,a,b,c,g,h,i,d,e,f) 
end 
addEventHandler("getTrain", getRootElement(), getTrain) 

Server side :

addEvent("setTrainPosition",true) 
function setTrain (x,y,z,a,b,c,g,h,i,d,e,f) 
    triggerClientEvent( "getTrain", getRootElement()) 
    setElementPosition(loco, x, y, z, false) 
    setElementPosition(locool, a, b, c, false) 
    setElementPosition(pilot1, d, e, f, false) 
    setElementPosition(pilot2, g, h, i, false) 
end 
addEventHandler("setTrainPosition",getRootElement(),setTrain)  

I don't know if that's what you wanted.
